Appendix A. Programming The Flash Memory Device; Introduction; Cfi Flash Memory Map - Altera Cyclone IV GX User Manual

Introduction

As you develop your own project using the Altera tools, you can program the flash
memory device so that your own design loads from flash memory into the FPGA on
power up. This appendix describes the preprogrammed contents of the common flash
interface (CFI) flash memory device on the Cyclone IV GX transceiver starter board
and the Nios II EDS tools involved with reprogramming the user portions of the flash
memory device.
The Cyclone IV GX transceiver starter board ships with the CFI flash device
preprogrammed with a default factory FPGA configuration for running the Board
Update Portal design example and a default user configuration for running the Board
Test System demonstration. There are several other factory software files written to
the CFI flash device to support the Board Update Portal. These software files were
created using the Nios II EDS, just as the hardware design was created using the
Quartus II software.

Altera recommends that you do not overwrite the factory hardware and factory
software images unless you are an expert with the Altera tools. If you unintentionally
overwrite the factory hardware or factory software image, refer to
